Included Orion Shorty 2x Barlow Lens adds versatility by doubling the magnification of each eyepiece in your collection - makes the included 7.5mm eyepiece provide the magnification of a 3.7mm eyepiece

The Orion Planetary Explorer Kit includes multiple items which will enhance your views of Earth's neighbors in the solar system. Most of the planets are nice and bright when visible in the sky, making them wonderful targets to train your telescope on. This affordable add-on kit will help you make the most out of planetary viewing sessions with the included Orion Set of Four Color Telescope Filters, 7.5mm Orion Sirius Plossl eyepiece, Orion Shorty 2x Barlow Lens, and the Orion Beginning Stargazers Toolkit.

Explore the planets with the included 7.5mm Sirius Plossl eyepiece.

Offering a wide 52° apparent field of view, the 7.5mm Orion Sirius Plossl Telescope Eyepiece provides extremely sharp images with impressively high contrast. It's ideal for all types of telescopes: reflector, refractor, and catadioptrics like Maksutov-Cassegrains. The Plossl 4-element design is renowned for its outstanding performance, and has become the standard by which all other telescope eyepieces are judged. The 7.5mm Orion Sirius Plossl Eyepiece is superb for high-power planetary and lunar observation, and is well suited to double-star viewing when stable seeing conditions permit.

Double your magnification options with the Shorty 2x Barlow Lens.

A 2-power (2x) Barlow lens is an extremely versatile eyepiece accessory that doubles the magnification of any eyepiece installed. For example, if you have a telescope with a 350mm focal length, using a 7.5mm eyepiece will yield a view with 46.7-power magnification. If you installed the same 7.5mm eyepiece into the Shorty 2x Barlow Lens and used the same 350mm telescope, your viewing magnification would be increased to 93.3-power magnification (46.7 x 2). What's more, the Orion Shorty 2x Barlow gets it's "Shorty" moniker from its compact size compared to other Barlow lenses, so it's easier to find a spot for it when packing your gear for a night under the stars.

Enhance subtle features with the included Set of Four Color Filters.

Because many planets have a characteristic color (e.g., Mars is reddish), a color telescope filter will reduce the predominant hues to enhance contrast and uncover hidden surface markings. That's why "the Red Planet" is most effectively enhanced with a green filter! The included Set of Four Color Filters comes with a foam-lined case. Here's a bit more information on each of the four included filters:

With the included Orion Beginning Stargazer's Toolkit, you'll never be "lost in space!" It contains four items designed to help astronomers find their way around the heavens.

Orion Star Target Planisphere

This handy star-chart wheel makes it easy to see "what's up" in the night sky any day of the year. Dial in your local date and time and it shows you the locations of the constellations and deep-sky objects in the night sky. You can even use the Orion Star Target planisphere chart to plan out a stargazing session in the future, or see what time of year your favorite constellation or star will be visible.

Discover the Stars guide book

A wonderfully written and illustrated observer's guide book which is a great reference for beginning astronomers and seasoned hobbyists alike. It's filled with useful and educational information on the wonders of the night sky. Perfect for reading on cloudy evenings when the stars aren't visible!

Orion MoonMap 260

The included Orion MoonMap 260 is a useful reference map of the Moon's surface that will help the whole family learn the names and locations of more than 260 craters, mountains, valleys, "seas" and other interesting lunar features you can explore with your telescope. Use the MoonMap 260 to identify craters you've observed, or use it before you go out with a telescope to plan a night full of Moon-watching family fun.

Orion RedBeam Mini LED flashlight

A red flashlight is needed to read materials and illuminate astronomy equipment at night. While a white flashlight would work too, it would decrease your dark-adapted vision at night, making it more difficult to get the most out of your observations. The Orion Redbeam Mini LED keychain flashlight emits pure red light that won't spoil your night vision. Perfect for reading your planisphere or seeing what you're doing at the telescope.

Warning

Please note this product was not designed or intended by the manufacturer for use by a child 12 years of age or younger.

Coatings

Binocular lenses and prisms are often coated with anti-reflective material to minimize light loss as light travels through the multiple optical surfaces of a typical binocular. Coatings help maximize the amount of light transmitted through each glass surface of a binocular, so as much light as possible reaches the observer's eyes to provide a bright and sharp image.

Good lenses are at least "fully coated," with a single layer of magnesium fluoride coating applied to each air-to-glass lens surface. Multiple layers of coatings are even more effective; the term "multi-coated" means one or more air-to-glass lens surface has multiple coatings. "Fully multi-coated" optics are even better, meaning all lens surfaces have multiple layers of anti-reflective coatings applied for maximum light transmission and optimal image quality.

Compression ring

Instead of a single thumb screw locking the eyepiece in place, a brass ring compressed by a thumb screw secures the eyepiece. This spreads clamping force over a larger area of the eyepiece's barrel, which provides a better connection. The compression ring also prevents the tip of the thumb screw from producing unsightly scratches and divots on the eyepiece barrel.

Having trouble viewing details on the Moons surface? This neutral-density eyepiece filter reduces glare so you can see more detail and surface features. The 1.25" Orion 13% Transmission Moon Filter is especially useful with large aperture telescopes.

Need to restore your optics to their original performance level? The Orion Optics Cleaning Fluid for Coated Lenses safely removes harmful oil and dirt from all coated lenses which increases resolution and light transmission.
